Welcome to the November 2009 issue of GL's Newsletter providing information on our Hand Held Portable Test Instruments. These units can test a wide variety of digital interfaces such as T1, E1, T3, E3, as well as asynchronous and synchronous data interfaces such as RS 232, RS 422, V.35, and X.21.

Overview

GL's hand held test instruments LinkTest™ SINGLE, LinkTest™ SINGLE+ and LinkTest™ DUAL are simple and easy to use bit error rate testers for almost any interface.

Brief description of products

LinkTest™ SINGLE

LinkTest™ SINGLE is a hand held portable unit supporting a single T1, E1 interface in addition to a host of other interfaces such as asynchronous or synchronous, Fractional T1, Fractional E1, modems, multiplexers, and CSU/DSUs. The LinkTest™ SINGLE has combined physical interfaces for V.35, RS232, RS422/RS530, X.21, DS1 (T1, 1.544 Mbps) and G.703 (E1, 2.048 Mbps). The tester is battery operated or can be used with a wall-mounted AC transformer.

Some of the Important features
